Tube Shell Heat Exchanger

Definition and Overview

The Tube Shell Heat Exchanger, also known as shell and tube heat exchanger, is a widely used industrial heat transfer device. It facilitates thermal energy exchange between two or more fluids flowing through separate channels. The main components include the shell, tube bundle, tube sheets, and baffles (or support plates), with the tube bundle serving as the core component for heat transfer between fluids.
